Something that could be interesting also is to remove VR and systemVMs logs
from the cloudstack-management.log and have them into a separate files. I'm
still not sure of those logs are traps only when there is problems, if it's
the case it make sense to keep them in  cloudstack-management.log.

Anyhow, it might be interesting to collect VR and systemVMs logs from the
management servers.

The log structure is also pretty stable so far which make integration with
ELK fairly easy which is good!

What about the catalina.out? is there any way to reduce is size?

I'll update the JIRA issue with problematic troubleshooting logs that are
not clear to interpret...

Thanks Paul for taking that one !
